Did Your Ranking take a nosedive after the Google Penguin and Panda Updates?Do you think your competitors are creating bad links just to tank your rankings?

What it is and when to use it?“The primary purpose of this tool is to help clean up if you’ve hired a bad SEO or made mistakes in your own link-building.”Can help with negative SEO.Now, Matt Cutts is saying in his video that “only If you’ve been notified of a manual spam action based on “unnatural links” pointing to your site, this tool can help you address the issue”. If you haven’t gotten this notification, this tool generally isn’t something you need to worry about.

I think that isn’t true and you should use this tool, if you have properly analyzed your links and you have figured out that you have some unknown links or some terrible spammy links, whether Google has contacted you are not.
